Improved lattice fermion action for heavy quarks
Yong-Gwi Cho, Shoji Hashimoto, Andreas Jüttner +4
We develop an improved lattice action for heavy quarks based on Brillouin-type fermions, that have excellent energy-momentum dispersion relation. The leading discretization errors…
Charm physics with Moebius Domain Wall Fermions
Andreas Jüttner, Francesco Sanfilippo, Justus Tobias Tsang +5
We present results showing that Domain Wall fermions are a suitable discretisation for the simulation of heavy quarks. This is done by a continuum scaling study of charm quarks in…
Scaling study of an improved fermion action on quenched lattices
Yong-Gwi Cho, Shoji Hashimoto, Jun-Ichi Noaki +4
We present scaling studies for heavy-quark observables calculated with an -improved fermion action on tree-level Symanzik improved gauge configurations. Lattices of $1/a =…
-improved actions for heavy quarks and scaling studies on quenched lattices
Yong-Gwi Cho, Shoji Hashimoto, Jun-Ichi Noaki +2
We investigate a new class of improved relativistic fermion action on the lattice with a criterion to give excellent energy-momentum dispersion relation as well as to be consistent…
Locality of the overlap-Dirac operator on topology-fixed gauge configurations
Yong-Gwi Cho, Shoji Hashimoto
We investigate the locality property of the overlap-Dirac operator on gauge configurations generated with extra Wilson fermions. By such extra terms we expect that the structure of…
